我的应用程序在Android版本2.3.3中工作没有任何问题但是当我在Galaxy S5(4及更多版本)上测试它时,它不起作用。

这是LogCat错误输出:

这是我的AndroidManifest

任何人都可以帮我解决吗?

2 个答案:

答案 0 :(得分:0)

好吧,所以马上看错误你可以看到问题。您正在主线程上进行联网。出于正当理由,这是不允许的,因为它会严重影响您的UI。现在有两种方法可以解决这个问题。

  1. 将您的网络请求放在不同的线程中,例如Async任务(如果您需要帮助,请发表评论)

  2. 关闭此功能。不推荐,但我想我至少会告诉你:

  3. StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);
    

答案 1 :(得分:-1)

您正尝试在主线程中运行Network。你试过添加吗?

if (android.os.Build.VERSION.SDK_INT > 9) {

  StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder(),permitAll().build();

  StrictMode.setThreadPolicy(policy);

}
